IMPROVEMENT IN STEAM FEED AND HOISTING APPARATUS.

Specification forming part of Letters Patent N0. 219,060, datedSeptember 2, 1879,; application filed July 7, 1879. V

. tlon.

The object of our invention is to bring the body to be moved moredirectly in connection with the steam or moving power. This weaccomplishrby attaching the piston-head to a metallic band or cable,which may be attached to a carriage or elevator without any othermachinery.

In the drawing the figure represents a side view of our inventioncomplete.

A A represent a cylinder, similar to an ordinary steamcylinder. m m is ametallic band or cable, passing through the cylinder and around theband-wheels L L. i

B B represent the cylinder-heads, each provided with an airtightpacking,through which the band m m passes.

O is a piston-head, rigidly attached to the band m min any suitable andsubstantial manner.

The head 0 may be made in two parts, each half made zigzag, so as to fittogether and crimp and hold the band m m.

E is a steam-chest, receiving steam through the pipe G and exhausting itthrough the pipe H. D is a movable cylinder-head, so arranged as to beheld in position by means of the pins 0 O, or to be crowded to the endof the cylinder, in order to allow a long or short stroke, at the willof the operator.

The head D is provided with an air-tight packing similar to the heads BB- The bandwheels L L are adjusted by means of the screw X, so as tostrain or take up the slack of the band on m. The pins 0 O are attachedto a lever, P, which has a bearing in fulcrum R, and is provided withthe spring S, which holds the pins in the position shown in the drawing.The pins 0 O are beveled, as shown, so that a pressure against them bythe piston-head (J will drive back the pins, and thereby relieve themovable cylinder-head D, and allow it to be driven before thepistonhead, the object being to prevent breakage.

The body to be moved may be attached to the band m m at a n.

F and F are feed-pipes for the long stroke. 13 is a feed-pipe for theshort stroke and F, a feed-pipe for the purpose of forcing D back to theposition shown in the drawing after it has been crowded to the end ofthe cylinder.

The operation of our invention is as follows The steam being introducedinto the cylinder through F the piston head 0 is driven toward the headD until the steam exhausts through F The steam now coming through Edrives 0 back in the opposite direction, thus giving the short stroke.For the long stroke the piston O is driven by the steam in: troducedthrough F until the steam exhausts through E, F being closed in themeantime.

When the head D has been driven to the end of the cylinder for the longstroke, and the operator desires to place it back for the short stroke,the steam is introduced through F, and D is quickly driven to theposition shown in the figure, where it will be held by pins 0 O.

The slack of the band maybe taken up by the device shown at n n.

The band 122 m may be made to run in any direction, and our device maybe used for moving carriages horizontally backward and forward, or forrunning elevators or lifting and lowering weights perpendicularly. 7

Having thus described ourinvention, what we claim to have invented, anddesire to secure by Letters Patent, is

1. The metallic band or cable in m, in connection with the piston-head Gand cylinder A A, the band passing through both heads of the cylinderand through the cylinder, for the purpose of conveying reciprocatingmotion direct to any body attached to such band, substantially as'described.

2. The combination of the adjustable cylin der-head D, band m m,piston-head G, and pins 0 0, when constructed substantially as (icscribed.
